"Application filed Kay 10, 1920, Serial No. 380,217. Renewed July 8,

My invention relates to cast metal wheels. The object of my invention is to produce a cast metal wheel of a type whose construction shall remain unchanged in theessential particulars when it is necessary to adapt the construction to v'aryingsizes of axles, bear- 'mgs, etc.

At the present time, cast wheels, and in particular cast steel wheels for automotive equipment, aresubject to the objection that radical modifications in the patterns must be made to fit each cast steel'wheel, to the particular type of axle and bearing with which the wheel is to be fitted according to the desire of the individual manufacturer of the automotive equipment. This seriously disturbs economical production in the foundry.

It is the object of my invention toprovide a wheel of such construction which will re-' Fig. 2 's a section taken on the line 2-2.- of Flg. 1;

Fig. 3' is a plan view of the rim' illustrating the barsv fortying the rim members together.

In these comprises a hollow hub having an inner tu bular wall 1- which is adapted to receive bearings and. an outer spoke supporting wall 2 connected to said inner Wall by a wall 3.

forming the outer end of the hub: The wall 2 is parallel to the axis of the hub and joins the wall 3 to the outer wall 4 of a spoke.

The relation of the wall 2 with respect to,

the spokes remains constant, while the distance between the walls 1 and 2, and consequently the lengt cording to the internal diameter of the hub which depends u on the particular axle and bearing which is ing used w1th this standdrawings my improved wheel.

h of the wall 3, varies acard type of wheel. The spokes are hollow and comprlse walls 4 and 5 substantially 1 parallel for a portion of their length and curved outwardly and upwardly, as shown.

at 6 and7: These outwardly and upwardly .curved portionsmerge with the wheel rim which is hollow and comprised of two'tread sections 8 and 9. These sections 8 and 9 terminate short of one another, leaving a.

gap 10, such gap being bridged at intervals throughout the periphery of the rim by tie bars 11. This separationof the rim treads permits easy truing up of the wheel. It will be noted that the tie bars 11 extend from and shocks to which the wheel is subjected. I0 I From the foregoing description .it will be seen that I have provided a wheel having a hub construction which' may; readily be changed to adapt it to different sizes of axles the other 78 and bearings without changin .dimenslons of the wheel, and arm having a divided tread reinforced to withstand the usual strains and shocks.

I desire to comprehend withln my invent1on such variations as may embodiment of it here illustrated.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:'

1. In a cast wheel, a hollow rim, hollow spokes and a hollow hub, with an innerutuwall, one wall of said hub being projecte laterally of the inner ends of the spokes.

2. A cast metal wheel comprising a hub, hollow spokes and a rim, the hub having an inner tubular wall to receive bearings and an outer spoke-supporting wall extendin bular wall and an outer spoke supporting beyond the spokes toward the outer end 0 the hub'to form a substantially cylindrical wall and merged into the walls of the spokes,

and a hub end wall joining said inner tubular wall and sald outer spoke supporting wall.

hollow spokes and a rim, the hub having an be within its .0 scope without limiting myself to the specific- 3. A cast metal wheel comprising a hub,

inner tubular wall to receive bearings end hub to support a bearing, and an outer spoke an outer spoke supportlng wall extendlng supporting well also extended beyond the 10 beyond the spokes to support the bearing at spokes at the outer end of the hub and the outer end of the hub. adapted to further snpport the bearing at 4:. A cast metal wheel comprising a hub, said end. hollow spokes and a rim, the hub having an In testimony whereof, I' afiix my signainner tubular Wall extended beyond the ture. spokes at the inner and outer ends of the GEORGE WALTHER.
